Dead Pixel Fixer
Try to revive a stuck pixel right in your browser. Start the repair, drag the patch of fast-flashing color noise over the bad pixel, and leave it to exercise the pixel back to life. It targets stuck pixels — not sure which you have? Run the Dead Pixel Tester first.
Photosensitivity warning
This tool rapidly flashes high-contrast colors. If you have photosensitive epilepsy or are sensitive to flashing light, do not use it. Flashing only starts once you press Start.
Drag the patch over the pixel · leave it 10–30 min
Works best on a pixel frozen on a color. A truly dead (black) pixel rarely recovers.
Drag the flashing patch right over the stuck pixel — full screen reaches the edges.
Leave it running for 10–30 minutes, and try a few separate sessions if needed.
How it works
A stuck pixel is one whose red, green, and blue sub-pixels are frozen instead of switching with the image. The fixer paints a small square with random full-color noise that changes roughly sixty times a second, so every sub-pixel under it is forced on and off again and again. That rapid exercise can free a sub-pixel that's jammed, letting it respond to the display signal once more. You drag the patch so the stuck pixel sits inside it and let it run — the longer the better, within reason.
Stuck vs dead pixels
The fix only works on stuck pixels — ones locked on a bright color because the sub-pixels still have power. A deadpixel stays black on every color because it has no power at all, and no amount of flashing will bring it back. If you're unsure, the Dead Pixel Tester tells them apart: a fault that's black on a white screen is dead, while one that glows a fixed color is stuck and worth trying to fix here.
For the best results
- Find the exact pixel first, then drag the patch so it sits squarely on top.
- Use full screen for pixels near the edges or corners of the display.
- Give it time — 10 to 30 minutes per session, and repeat across a few sessions.
- On OLED, keep sessions short rather than leaving it on for hours at full brightness.
- If several attempts do nothing, the pixel is most likely dead, not stuck.
Frequently asked questions
Can a dead pixel actually be fixed?
It depends on the type. A stuck pixel — one frozen on a color like red, green, or blue — still receives power, and rapidly cycling it through colors can sometimes nudge it back to normal, so these have a real chance of recovery. A truly dead pixel stays black because it gets no power at all, usually from a broken transistor, and software can rarely revive it. This tool is aimed at stuck pixels; it's worth a try on a dead one, but don't expect much.
How does flashing colors fix a stuck pixel?
A stuck pixel is one whose sub-pixels are locked in position instead of switching as they should. Flooding the area with rapid, random red-green-blue changes forces those sub-pixels to switch on and off many times a second, which can unstick the liquid crystal and let it respond to signals again. It's essentially exercising the pixel — the same idea behind long-standing tools like JScreenFix. There's no guarantee, but it's harmless to try and works often enough to be worth the time.
How long should I run it?
Position the flashing patch over the stuck pixel and leave it running for at least 10 minutes; 20 to 30 minutes gives it a better chance. If nothing changes, exit and try again later — several separate sessions sometimes succeed where one long run doesn't. If the pixel hasn't budged after a few attempts, it's probably a hardware fault that a software fix can't reach.
Is this safe for my monitor, and what about OLED screens?
For LCD panels the risk is minimal — you're just changing colors quickly, which the screen does constantly anyway. On OLED, avoid running it for hours on end at maximum brightness, since prolonged static-bright content is best avoided on those panels; short repair sessions are fine. The main caution isn't the screen, it's you: the rapid flashing can affect people with photosensitive epilepsy, so skip it if that applies to you.
Does it work on phones, laptops, TVs, and OLED?
Yes — it runs in any modern browser, so it works on phones, tablets, laptops, monitors, and smart TVs, on both LCD and OLED. Use full-screen mode and drag the patch right over the affected spot; on a phone, touch and drag to position it. For pixels near the very edge of the screen, full screen is important because it lets the patch reach all the way into the corners.
What if the fixer doesn't work?
If repeated sessions don't help, the pixel is likely dead rather than stuck. Some people try the gentle-pressure method — with the screen off, press very lightly on the exact spot with a soft cloth, then turn it back on — but this carries a small risk of causing more damage, so weigh it carefully. If the panel is under warranty, check the manufacturer's dead-pixel policy, as a defect may qualify for a repair or replacement.
